vim：在注释中缩进 bullet/lists（在 python 中）

Question

vim 文本文件中的缩进列表（或项目符号）很好：

- this is item one that 
  is indented correctly
- this is item two that 
  is also indented 
  correctly

我可以在上面的段落中键入 gqap，并且格式和缩进工作正常。

但是，这在 python 评论中不起作用，并且缩进如下：

# - this is item one that 
# is not indented correctly
# - this is item two that 
# is also not indented 
# correctly

如果我在上面的 python 评论中键入 gqap，vim 甚至无法识别要点。并最终将整个块格式化为段落。

那么关于项目符号和缩进，我如何让 vim 在 python 注释中的行为方式与在常规文本文件中的行为方式相同？

Answer 1

这实际上是一个非常困难的问题，尽管 formatlistpat 对它有很好的支持，但没有明显的记录。通过将 formatlistpat 和 formatoptions 确定为我想在我的 vimrc.

中使用的设置，我能够支持多种样式的列表

您可以通过以下方式获得完整的概览：

:help 'formatlistpat'
:help 'formatoptions'

您的工作示例表明您喜欢 vim 转换以下：

- this is item one that 
is indented correctly
- this is item two that 
is also indented 
correctly

通过在正常模式下输入 gqap 或 gqip，您将获得以下信息：

- this is item one that is indented correctly
- this is item two that is also indented correctly

但是有一个问题，如果你看到类似下面的内容，你无法在 vim 中使用你的配置缩进无序列表：

# - this is item one that 
# is not indented correctly
# - this is item two that 
# is also not indented 
# correctly
# + this is item one that 
# is not indented correctly
# + this is item two that 
# is also not indented 
# correctly
# * this is item one that 
# is not indented correctly
# * this is item two that 
# is also not indented 
# correctly

在这种情况下，gpaq 将错误地格式化为以下内容：

# - this is item one that is not indented correctly - this is item two that
# is also not indented correctly + this is item one that is not 
# indented correctly + this is item two that is also not indented  
# correctly * this is item one that is not indented correctly * this 
# is item two that is also not indented  correctly

您可以通过以下方式立即更正此缩进问题：

:set formatoptions+=n
:set formatlistpat=^\s*[\-\+\*]\+\s\+

这将按照您想要的方式重新格式化您的评论：

# - this is item one that is not indented correctly
# - this is item two that is also not indented correctly
# + this is item one that is not indented correctly
# + this is item two that is also not indented correctly
# * this is item one that is not indented correctly
# * this is item two that is also not indented correctly

还有其他您不想支持的列表：

# a) this is item one that is not
# indented correctly
# b) this is item two that is also not
# indented correctly
# C. this is item three that is also not
# indented correctly

可以正确格式化为：

:set formatlistpat=^\s*\w[.\)]\s\+

以下：

# 1 this is item one that 
# is not indented correctly
# 2) this is item two that 
# is also not indented 
# correctly
# 33. this is item three that 
# is also not indented 
# correctly

可以正确格式化为：

:set formatlistpat=^\s*\d\+[.\)]\s\+

以下：

# i. this is item one that 
# is not indented correctly
# ii. this is item two that 
# is also not indented 
# correctly
# iv) this is item three that 
# is also not indented 
# correctly

可以正确格式化为：

:set formatlistpat=^\s*[ivxIVX]\+[.\)]\s\+

您可以用简单的两行将所有内容放在一起：

:set formatoptions+=n
:set formatlistpat=^\s*\w\+[.\)]\s\+\\|^\s*[\-\+\*]\+\s\+
